摘要:

漆蓝卷象Involvulus haradai(Kono)是橄榄的一种新害虫,中国昆虫新记录种。成虫吸食危害橄榄嫩梢、果实汁液,严重影响树势生长、果实品质和产量,5a生橄榄产量损失可达45%。该虫在福建平和1a发生2代,幼虫在受害后的枯梢中取食,大多以老熟幼虫在土壤中1~7cm深处筑土室滞育越冬,翌年4月下旬成虫开始出土危害。山坡下部比上部橄榄受害重;晚春梢和夏梢受害重,秋梢受害较轻。

Abstract:

Involvulus haradai (Kono) is a new recorded species of the family Attelabidae, Coleoptera, in China injuring trees of Canarium album and Rhus chinensis. The adult damages the tender tops and sucks the fruit juice of C. album decreasing the tree momentum growth, fruit quality and yield. The yield loss of 5-year-old C. album may reach to 45%. The pest has 2 generations per year in Pinghe, Fujian Province. The larvae damages tree tips inside and lead them withered. When full grown the larva builds a cell in the soil at a depth of 1~7cm and over winter there. The adults emerge in the end of April next year.C. album damages more seriously at lower part of the hillside. Within the tree's seasonal growing period, the late spring and summer shoots are damaged more serious than the autumn ones.

Key words: Involvulus haradai, Morphological characters, Bionomics, Canarium album
